SPECIFICATION formingpart of Letters Patent No. 698,024, dated April 22,1902.

Application filed March 24, 1902. $erial No. 99,619. (No model.)

and its object is to produce a ball which shall a long distance whenstruck a hard blow fly by a club, but which shall be practically deadwhen given a light tap, thereby meeting all the requirements of the gamein question.

In the accompanying drawings, Figure 1 is a view, partly in section, ofa ball made in accordance with my present improvements. Fig. 2 shows afabric cup or hemisphere which is preferably used in practicing myinvention.

Fig. 3 shows, partly in section, a ball wound with rubber threads undertension and inclosed in a pair of cups of the Fig. 2 kind; and Fig. 4illustrates the process of finishing the ball.

For the core of the ball I employ a spherical body made of windings ofrubber thread A, the thread being wound under high tension,

preferably upon a small gutta-percha center piece B. A core thus formedis highly elastic and has excellentdriving qualities, but is too elasticfor light blows or putting. To

correct this fault, I inclose the sphere A in an envelop. of fibrousmaterial, preferably by placing thereon hemispherical cups 0 and D,preferably of rather heavy woven fabric, and

the ball thus formed I then inclose in segments of gutta-percha E and F,which I place in the finishing-dies G and H, the gotta-percha beingheated and the dies being brought together with great force, so as tocompress the shell forcibly upon the inclosed sphere A,

the pressure of the dies being maintained while the shell cools andhardens, so that the latter in the finished ball holds the core as thusinclosed in a powerful grip.

It is found in practice that a tensionedthread sphere A, provided Withthe fabric 0 and covered with a gutta-percha shell E, as described, hasphenomenal'fiying qualities, while 'being dead when given a light blow,thereby admirably adapting it for all the requirements of the game.

Variations may be made within the scope of my invention.

Having described my invention, I claim '1. A playing-ball comprising aspherical body consisting of rubber threads under tension, a fabriccovering upon said body, and a gutta-percha shell upon said fabriccovering.

2. A playing ball comprising a sphere which consists of tensioned softrubber, a shell consisting entirely of gutta-percha lined with fabricand inclosing said sphere.

3. A playingball comprising a sphere which consistsof tensioned softrubber, and a shell consisting entirely of gutta-percha lined withfabric and inclosing said sphere and holding said sphere undercompression.

4. A playing-ball comprising a spherical body consisting of tensionedrubber threads, and a fabric-lined shell of gutta-percha com= pressedupon said spherical body.

5. A playing-ball comprising a spherical body consisting of tensionedrubber threads and a fabric-lined shell ofgutta-percha compressed uponsaid spherical body, said shell consisting of segments of gutta-perchaand fabric which are united at their edges.

6. A playing-ball consisting of a spherical bodyof soft rubber undertension, a fabric covering thereon, and segments of gutta-percha weldedat their edges and compressed upon said spherical body.

7. A playing-ball comprising a soft=rubber spherical core inclosed in anenvelop of fabric, and an outer inclosing covering of gutta-perchacompressed upon the ball.
